Honestly all the main characters over-react to the big revelation in my opinion. I found it hard to swallow, the idea that people living in a feudal/renaissance era society would feel guilty about their ancestors winning a war thousands of years ago, taking the land of the conquered, and then enslaving them. Those events were common historically and people usually wrote epic poems about how great their ancestors were for doing that. The human societies don’t seem to have a reason for their morality to be so modern.
